When I change the keyboard type in the file /etc/default/keyboard,
and after restarting the service, udev does not reflect the change,
until that I execute

udevadm trigger && udevadm settle

I think that the setupcon program should call udevadm after setting a new
keyboard layout,

tag 568645 help
severity 568645 minor
thank you

Strictly speaking setupcon means 'setup console' and this doesn't
suppose that udevadm has to be called.  Because of this I am lowering
the severity to 'minor'.  On the other hand I agree that this can be
useful.

The reason I am not going to fix this is that I am not well acquanted
with the udev/hal system.  I understand that the patch to fix the bug is
very simple but sometimes to maintain a one-line code and to fix all
problems that could arise in the future requires more than simply
understanding what this one-line command does.  There is no way back -
if this functionality is added to setupcon the users will expect it so
it would be impossible to revert the change.  Correspondingly I am
adding a 'help' tag to this bug and leaving for some other developer to
fix it.

No package should call "udevadm trigger", ever.
At most, if this is actually needed by the package, the command used
should be something like "udevadm trigger --action=change
--xxxxx-match=yyyy" with the appropriate options to restrict the events
to only the right devices.

I see no reason to call "udevadm settle" either in this scenario.

Hello,

following those directives, could be:

udevadm trigger --action=change --subsystem-match=input

I have written the attached patch to solve that,

the X server uses the keyboard layout specified by udev,
changing the console keyboard also implies the keyboard layout used by the X
server,
after the change, restarting the services has no effect on the X keyboard until
we update udev, or rebooting the complete OS.
